Question

The production of eye-color pigment in Drosophila requires the dominant allele A. The dominant allele P of a
second independent gene turns the pigment to purple,
but its recessive allele leaves it red. A fly producing no
pigment has white eyes. Two pure lines were crossed
with the following results:
P red-eyed female  white-eyed male
F1 purple-eyed females
red-eyed males
F1  F1
purple eyed 3
8
red eyed 3
8
white eyed 2
8
F both males and females: 2
Explain this mode of inheritance, and show the genotypes
of the parents, the F1, and the F2.

P.
red-eyed female x white-eyed male

Explain this mode of inheritance, and show the genotypes
of the parents, the F, and the F2.
